@Barrgi I tried it too, with the same result. I decided to ask Meta AI for a solution. It suggested I add the Ublock Origin extension to Opera, then to add the following code lines to the filters in the dashboard: facebook.com##.ticker_stream
facebook.com/ajax/pagelet/generic.php##

I did this about ten minutes ago. To begin with, it sort of worked. I jumped tabs for five minutes, and I came back to a refresh button option, which I was able to ignore. Then I did another five minutes, and it automatically refreshed when I jumped back, so it would seem I need to find some more Facebook filters. The AI did have other suggestions, so I'll do some more research, based on what it said. If I come up with anything that works consistently, I'll post another reply in this thread.

The AI also recommended that users provide feedback to Facebook, that Facebook should give people the option to disable the auto-refresh function within Facebook settings. I suggest we all do that. If enough people say it, then they might listen, as it's alienating a lot of users. The AI thought it might be a misguided attempt to keep users engaged! You've got to love its honesty.
